氧氮氢分析仪的使用注意事项:
1 、氧氮氢分析仪在初次启用前,应该对连接点、焊点、阀门等进行检漏,以确保空气中的氧不会反渗进入管道及仪器内部,造成测量数值偏高。
2、再次使用仪器前,要进行管道系统净化,将漏入的空气除干净,同时确保连接取样管路时没有漏入空气。
3、样气中氧含量的变化会受管道材质及表面粗糙度影响,因此一般连接管路选用铜管或抛光过的不锈钢管,而不用塑料管、橡胶管等。
4、微量元素分析时,要避免各种管件、阀门、表头等死角对样气造成污染,因此必须尽可能的简化气路系统,连接件死角要小,以防止溶解氧逸出造成污染,使用水封、油封及腊封等设备,才能较好的确保数据的。

Method Selection
Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.

Procedure - Solid Samples
Instrument calibration/drift correction.
Place the calibration/drift standard in a *** Nickel Basket, and if applicable, place the sample into the appropriate autoloader position.
Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open.
Note: samples using automation should be placed in the appropriate autoloader position before starting the
analysis sequence. Once the sequence has started, the automatic analysis will start and end automatically.
